-Haversack of Holding: 4 types, all allowing the haversack to hold as much as a bag of holding of the respective type.

-Horrific Haversack: Comes with a command word and turns into a haversack-wood-golem if it is used sans uttering it.

-Homogeneous Haversacks: Set of haversacks that share the same extradimensional space - if you can't craft a great smuggling plot from these, I can't help you. These are awesome!

Conclusion:
Editing and formatting are top-notch, I didn't notice any glitches. Layout adheres to SGG's 3-column landscape-format and the pdf has no bookmarks, but needs none at this length. The haversacks herein are smart, balanced and while the extradimensional haversacks should remain rare in order to not upset your campaign's economics. That being said, the haversacks herein are solid, cool and provide you with tools to make good stories. The Bag of Holding-haversacks are lazy in my opinion, though. Thus, I'll settle for a final verdict of 4.5 stars, rounded down to 4 for the purpose of this platform.
